XST - "ERROR:HDLParsers:1209 - .vhd Line xx. : Undefined symbol (last report in this block)"

Description

General Description:

When I synthesize a VHDL design with XST, the VHDL parser issues the following error:

"ERROR:HDLParsers:1209 - <file>.vhd Line xx. <inst>: Undefined symbol (last report in this block)"

Why is this error message occurring?

Solution

This message is followed by similar messages: "HDLParsers:3312" and "HDLParsers:3313". The messages indicate that multiple instances of the unknown component have been found, and rather than reporting the same message many times, the errors are stopped to save report file space.
